MU LTIPLE TOOL.

SPECIFICATION forming part of Letters Patent No. 435,890, datedSeptember 2, 1890.

Application filed November 27, 1889- Serial No. 331,829. (No model.)

To all whom it may concern:

Be it known that I. RHoDoLPH H. FRANK- LIN, a citizen of the UnitedStates, and a resident of Brooklyn, in the county of Kings and State ofNew York, have invented new and useful Improvements in Multiple Tools,of which the following is a specification.

My invention relates more particularly to screw-drivers forwatch-makers, jewelers, and other such light work; but is applicable toother tools, as brad-awls and the like; and it consists of a contrivanceof several of such tools of different sizes in a hollow handle, so thatany one may be readily shoved out of one end and secured in the positionfor use bya chuck while the rest are retired and confined within thehandle, all as hereinafter fully described, reference being made to theaccompanying drawings, in which Figure l is a side elevation of myimproved tool. Fig. 2 is a longitudinal section of the same with someparts of the case in side view. Figs. 3 and l are transverse sections onlines a: and 1 7 respectively. of Figs. 1 and 2 on an enlarged scale;and Fig. 5 is an end view without the chuek-nut, also enlarged.

I provide ahollow metal case or stock a with a taper split andscrewthreaded lower end Z1, forming jaws of a chuck, and fit on saidjaws a taper-threaded nut c, to contract the jaws on the screw-drivers,awls, or other like tools (Z to be used, and make two or morelongitudinal slits e in said case at uniform distances apart cireumferentially and extending nearly the whole lcngth,but terminating a littleshortof each end, one for each tool, which I make with a lateral spurfat the upper end to extend through one of the slits of the case for aprojection whereby the tool can be shoved out when required for use andback when not required, and in such a case I arrange as many tools (Z asthere are slits side by side, the said tools being of such size as willallow them all to be drawn back one by the side of the other within thecase, and the spurs being of such length as will allow the tools to cometo the center of the tube when shoved out for use, and having a head 9at the outer end wider than the slit to prevent the tool to which itbelongs from dropping farther into the tube and wedging in between theother tools, some of which, being smaller than the others in part oftheir length, leave so much space in the tube, especially below theupper portions, which are all of the same size that such result mightoccur except for the heads. The upper portions are all of maximum sizefor such length as is gripped by the chuck, in order that the chuck mayhave uniform range of opening and closing for all. At the upper ends ofthe slits they are enlarged a little, as at 00, to allow the heads ofthe spurs to be inserted through them from the inside, the tools beingdropped in from the upper end of the case, and these enlargements arethen covered by the short tube h, subsequently fitted and secured on theupper end of the case suitable for covering them. This short tube hasshort slitsz' in its lower end coinciding with the slits in the case andtapering upward to receive the spurs f of the tools and hold them bywedging them when forcibly drawn back, both for holding the tools not inuse up out of the way of the one to be shoved down into the chuck andfor drawing the tools laterally to their respective sides of the case,this latter action being effected by the heads of the spurs running onthe greater radial surface of the tube 72 For tools of the kindrepresented, which is a jeweler-s screw-driver, the case is fitted withthe ordinary rotating finger-cap Z on the upper end, enabling the toolto be rotated by the thumb and second finger while being pressed on theend by the first finger of one hand; but t-hisisnotmyinvention. It maybeused together with my improvements or not.

lhe spring-jaw part b of the chuck is connected to the case aby itsupper end inserted for a short distance in the end of the case, and thebore is bell-mouthed at the upper end to facilitate the entering of thetools to the center bore of the chuck.

\Vhat I claim, and desire to secure by Letters Patent, is

1. The combination of the cylindrical hollow slotted case, the grippingand releasing chuck on one end of the case, and two or more toolsinclosed in the case and having a lateral spur projecting through a slotand being capable of sliding out and projecting from the chuck, and alsobeing Withdrawn into the case and shifted laterally therein.

2. The combination of the slotted case, a chuck on one end of the case,two or more tools inclosed in the case and having a lateralspurprojecting througha slot and being capable of sliding out andprojecting from the chuck, and also being Withdrawn into the case, andthe short tube on the upper end of the case having the taper slitscoincident with the slots of the case.

3. The combination of the slotted case, the gripping and releasing chuckon the end of the case and central thereto, and two or more toolsinclosed in the case and having a lateral spur projecting through a slotof the case and being capable of sliding out and projecting from thechuck, and also being Withdrawn into and shifted laterally in the case,substantially as described.

4. The combination of the hollow cylindrical slotted case, the grippingand releasing chuck on the end of the case and central thereto andhaving the bell-mouth in the end inserted in the case, and two or moretools inclosed in the case and having a lateral
